Reaction Steps

Following the procedure described for Example 1(A), Step A, 2-[1-(3-benzyloxy-phenyl)-5-oxo-4,5-dihydro-2,3,6,10b-tetraaza-benzo[e]azulen-6-yl]-N-isopropyl-N-(6-methoxy-pyridin-3-yl)-acetamide (Preparation 6) (129 mg, 0.219 mmol) was condensed with 1H-indole-3-carbaldehyde (70 mg, 0.48 mmol). Purification by medium pressure chromatography eluting with a solvent gradient (10% EtOAc in hexanes to 100% EtOAc) yielded 60 mg of 2-[1-(3-benzyloxy-phenyl)-4-1H-indol-3-ylmethylene)-5-oxo-4,5-dihydro-2,3,6,10b-tetraaza-benzo[e]azulen-6-yl]-N-isopropyl-N-(6-methoxy-pyridin-3-yl)-acetamide. 1H NMR (CD3OD) δ 8.13 (m, 1H), 7.64 (m, 2H), 7.23-7.48 (m, 3H), 7.13 (m, 3H), 6.93 (m, 2H), 4.94 (m, 2H), 4.85 (m, 1H), 4.63 (m, 1H), 4.20-4.40 (m, 1H), 3.96 (m, 1H), 3.85 (d, 1H), 0.90-1.05 (m, 6H); MS 716.5 (M+1), 714.6 (M−1)
